ADJUSTABLE SUPPORT FOR WIRE MATTRESSES.

l SPECIFICATION forming part of Letters Patent No. 375,432, datedDecember 27, 1887.

Application tiled June 24, 1887. Serial No. 242,400. (No model.)

.To @ZZ whom it may concern:

Be it known that I, JOHN S. WERTZ, a citizen of the United States,residing at Burlington, `in the county of Des Moines and State of Iowa,have invented a new and useful Improvement in Adjustable Supports forWire Mattresses, of which the following is a specification.

I VIy invention relates to an improvement in adjustable supports forwire mattresses; and 1t consists in the peculiar construction andcombination of devices that will be more fullyset forth hereinafter, andparticularly pointed out in the claims.

The object of my invention is to provide a light, cheap, and portablesupport adapted to be attached to the frame of the mattress, and bearunder the mattress to prevent the latter from sagging.

In the drawings, Figurel is a top plan view of a mattress provided witha support embodying my improvements, a portion of the mattress beingremoved in order to disclose the support. Fig. 2 is a Verticallongitudinal sectional View taken on the line x .r of Fig. 1. Fig. 3 isa vertical transverse sectional view taken on the line y y of Fig. l.Fig. 4 is a de# tail view of the upper coil of the spring H.

A represents a wire mattress of vthe usual form, having the frame B,which comprises the transverse end bars, C, and the longitudinal sidebars, D, on which the ends of the bars C are secured.

E represents the frame of the support,which comprises a pair oflongitudinal side bars F and a number of crossbars, G, which have theirends secured on the under edges of the bars F. j

H represents a series of coiled supportingsprings which are arranged onthe bars G. In the upper coil of each spring is formed an opening, I,and the free end of each spring is provided with a hook, K, adapted toengage the said opening. The hooked end of each spring is passed throughthe upper coil of its Vcompanion spring, and is then caused to en- Lrepresents a series of supporting-brackets,

which are right-angular in shape, and are provided at their lower endswith inwardly-ex- The frame E is arranged transversely between A theside bars of the mattress-frame at any desired point, and the bracketson the ends of the frame E are caused to engage the upper edges of theside bars of the mattress-frame, as shown, so as to support the frame Ein place. The springs on the frame E bear under the mattress and preventthe same from being stretched and-caused to sag when in use.

It will be readily observed that the supports may be movedlongitudinally on the mattress A,so as to cause the supporting-springsto bear under any desired portion of the mattress.

It will be seen that the angle-arm brackets L merely rest on the upperfaces of the sides of the mattress-frame, and thus the entire supportmay be adjusted along the mattress-frame to any point desired, the armsL sliding readily along the side bars of the mattress-frame. The supportcan thus be adjusted to suit the occupant of the bed.

Having thus described my invention, I claini 1. A support forspring-wire mattresses, comprising the frame E, adapted to lietransversely between the side bars of the mattressframe, and having thelongitudinally-adjustable bracket-arms L, adapted to engage the sidebars of the mattress-frame, and the interlocking springs attached toframe E and adapted to bear under the wire mattress, substantially asdescribed.

2. A support for spring-wire mattresses, comprising the frame E, havingthe supporting-springs II thereon, the right-angled brackets L, havingthe slotted arms M arranged under the ends of frame E, and the boltsO,pass ing through the frame E and the slotted arms of the brackets,tosecure the latter to the frame ICO at any desired adj ust-ment,substantially as described.

3. The combination, with the wire mattress having the frame providedwith the side bars, of the supporting-frame, having thelongitudinally-adjustable bracket-arms secured thereto and adapted toengage the side bars of the mattress-frame, and the supporting springs4ar-Y ranged on the upper side of the supportingframe and bearing underthe wire mattress, substantially as described.

4. In a support for a wire mattress, the herein-described removablesupport, comprising the frame E, adapted to be placed between the sidebars of the mattress and to bear at the sides against the sides of saidmattress, said frame carrying the interlocking snpportingsprings to bearunder the mattress, and the bracket-arms L, angular in form, adjustablysecured to the frame E, and having their ends resting on the upper facesof the side bars of the mattressframe, as set forth.

5. In combination with the wire mattress A, the herein-describedremovable support therefor, comprising the frame E, composed of a seriesof slats, and the springs H, secured to l the slats,said frameE beingplaced within the side bars of the mattress, and having its springs Hbearing under the Wire covering of the mattress, and the angle-arms L onthe side of the frame E, to take over the upper faces ot' the side barsof the mattress-frame, whereby the support E can be shifted along underthe mattress-frame to any point desired, as set forth.

6. In combination with the mattress-frame, the hereindescribed removablesupport, comprising the frame E, having the supportingsprings H, andarranged under the mattressframe so that said springs H will bearagainst the under side of the wire covering of the mattress, the sidesof the support E havinga sliding connection with the side bars oftheinattress-frame, whereby said support may be slid along under themattress to any point desired without removing any part, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.
